I tried this in both 2022 and 2023, and did not have any clipping - tested with 16-bit and 24-bit. One thing that can affect this is having any of the faders in the mixer set above 0 (or 90 when reading MIDI values), or the master faders at the bottom of the mixer (see the screenshot below). If any of the faders are above zero, this will affect the rendered files, and it will be made worse when using the normalizer to increase the volume of each track.

You might not have heard clipping when playing the song back in BIAB, as BIAB has a built-in peak limiter, which will stop the audio from clipping. That limiter is only used when playing back, not when rendering - this is because users might want to use their own plugins for compression and limiting.

Where is that then? I don't see any normalise settings in the BIAB export audio section. In any case "normalise" is "normalise", i.e. amplify the wave so that the highest peak level is at digital FSD.

There are different ways to normalize audio. BIAB normalizes the loudest peak to 0dB FS. Other normalizers have settings to normalize to any dB level you choose, and some allow you to normalize to an RMS value.

The audio files for BIAB typically use dynamic compression, so they don't usually use the full dynamic range anyway. If you were to render two files, one with normalization and one without, they would be able to completely null each other in a null test - in other words, apart from an amplitude offset, the audio is bit-for-bit exactly the same either way.

I read ricobasso's original post as meaning each individual track was clipping in isolation. Is that the case rico, or are all the tracks summed together clipping?
